Although he wasn't Sicilian, Hagen proved himself to be invaluable to the Corleone family. He arranged countless hits for his bosses and advised them successfully through several mob wars. He also had a string of corrupt judges and government officials in his pocket. He even foresaw drugs as the future of organized crime. And let's not forget the horse head.

When you're Satan himself, pretty much any job you do will be smattered with evil. John Milton in the "The Devil's Advocate" is no exception.

This villainous lawyer doesn't mess around when it comes to getting what he wants. He dispatched hell-spawned muggers to kill a meddling managing partner. He raped his son's wife and even tried to trick him into "getting busy" with his half-sister in order to bring about the Antichrist.

While it's hard to top the devil, leave it to "The Wire" to prove the impossible time and time again.

Maurice Levy manages to represent everything society hates about lawyers and people in general. He had no qualms representing the likes of Marlo Stanfield, the Barksdale organization, and every other drug kingpin eager to prey on addicts. He also holds the distinction of being one of the few characters to make it through the entire series unscathed.
